Configure audio encoding

Configure audio encoding

If your channel includes audio sources in any of the layouts, then 

AAC 48 kHz

 is set as the default audio 

codec for the channel. You can choose a different audio codec for a channel using the Admin panel. The 
following table lists the supported audio codecs and bitrates.

Table 42 

Supported Audio codecs and bitrates

Value

Description

AAC

The AAC (default) audio codec is comparable to MP3 and may produce better 
sound quality with a similar bit rate. Supported values are 16, 22, 44 and 48K kHz. 

Most digital signals (HDMI or SDI sources) use 48 kHz audio. Matching the encoded 
level with the source level provides the best sound quality by avoiding audio 
resampling. For analog signals, 44 kHz provides  higher sampling.

The maximum bitrate for mono encoding of a 44 kHz signal is 264 kbps. For stereo, 
320 kbps is supported. Note that lower bitrates (e.g. 32 kbps) with a 44 kHz signal 
may result in distorted audio.

MP3

MP3  provides a common audio format for audio storage. Supported values are 22 
kHz, 44 kHz and 48 kHz. 

Most digital signals (HDMI or SDI sources) use 48 kHz audio. Matching the encoded 
level with the source level provides the best sound quality by avoiding audio 
resampling. For analog signals, 44 kHz provides  higher sampling.

Flash (FLV) doesn't support 48 kHz MP3 audio. When selecting this 
value you'll need to use a media player to preview your channel.

PCM

Pulse Code Modulation (PCM) is a standard for digital audio in computer and other 
devices such as, digital telephone systems. 

Most digital signals (HDMI or SDI sources) use 48 kHz audio. Matching the encoded 
level with the source level provides the best sound quality by avoiding audio 
resampling. 

Flash (FLV) doesn't support 48 kHz PCM audio. When selecting this 
value you'll need to use a media player to preview your channel.
